yes. is it up on the bloodline traits yet? if not could you give a discription of it? it doesnt have to be too long

Can i have my own keke genkai it won't be llike overdoing things very fair as well o.o

ya, that's fine. Just post the specifics here. And if there are different levels to it, start out at the first level so you have something to work for
and to answer your other question, you may start rping whenever. Just know that there aren't many people yet and(if you want) you can come and rp in my village, iwagakure, I'm a little bored. XD
